[PATCH 0/4] ARM: dts: meson8b: add VDDEE / mali-supply

[Martin Blumenstingl]

EC-100 and Odroid-C1 use a "copy" of the VCCK regulator as "VDDEE"
regulator. VDDEE supplies the Mali GPU and various other bits within
the SoC.

The VDDEE regulator is not exclusive to the Mali GPU so it must not
change it's voltage. The GPU OPP table has a fixed voltage for all
frequencies of 1.10V. This matches with what u-boot sets on my EC-100
and Odroid-C1.

Dependencies:
- compile time: patch #4 depends on my other patch "ARM: meson8b-mxq:
  better support for the TRONFY MXQ" from [0]
- runtime: we don't want the kernel to change the output of the VDDEE
  regulator to the maximum value. Thus the PWM driver has to be able
  to read the PWM period and duty cycle from u-boot. This is supported
  with my series called "pwm-meson: cleanups and improvements" from [1]
